By reporting memory usage of rust objects back to SM it can trigger GC
sooner and release more memory (I hope that we could use this to avoid
OOB in webgpu in the future).
Currently we use simple `size_of::<DomStruct>() +
size_of::<Box<DomStruct>>()` but it's possible to override reported
memory with `update_memory_size(self, nbytes);` on reflector. This is
mostly useful for canvases and buffers which usually have large
associated data.
Testing: None, but I am wondering if we can connect this to
`about:memory`.
Fixes: #42168

This breaks the `script_traits` dependency on `webgpu`. In general, the
`traits` crates shouldn't depend on Servo non-`traits` crates. This is
necessary to move "script to constellation" messages to the
`constellation_traits` crate, making it the entire API for talking to
the
constellation. This will break a circular dependency when that happens.
Testing: Successfully building is enough of a test for this one as
it is mainly moving types around.
